To all whom 'it may concern.- v

Be it known` that I, Lewis P. DAYTON, of North Buffalo, in the county ofErie, and State of New York, have' invented a certain new and usefulImprovement in Trusses; and I dn hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, making part of this specification. i

Figure 1 is a plan view of a truss, showing my improvement.

Figure 2 is an elevation of the hinge and the graduating-screw.

Letters of reference indicate corresponding parts in both figures.

My invention consists in forming the truss in .two parts, and combiningtherewith a hinge and an adjusting-screw, by which the pressure of thepad is regulated at pleasure,- as hereinafter set forth. y

In the drawings,

A A represent the ordinary springetruss, formed in v two pieces, andhinged at B.

One side has a projecting lug, O,for1,ned'on it, making one part of thehinge.

l) represents the opposite lug, making the other part ofthe hinge.

The tirst has a thumb-screw, ai, passing through the projecting part ofthe top, arranged for that purpose, and the end of the screw comes incontact with a similar projection (except that it is solid) of piece D.As the screw is turned, the end presses against the piece D, andnarrowsthe circle of `the truss, and, consequently, presses the padm'ore firmly against the rup-` tured part.

When the screw is turned the other way, it, of course, widens the circleof the truss, and decreases the pressure ofthe pad. i

u re, especially when. the person sits down, and. when the abdomen, forthat reason or some other, is so distended as to render the pressureunpleasant.

By having the hinge and screw so arranged, and the truss properly adjusted, the wearer can, at any timein the street, while walking, as wellas while 'sitting in the house-adjust the pressure, by merely puttinghisthe screw up or down, as desired, and it can be done in an instant,without attracting attention. A l
